About Me:

Many years ago I used to build my own autopilots from scratch as a hobby. Now I work full time in drones at CyPhy works!


Please tell us a bit about your UAV interest

Miss the days when you had to make your own autopilot from scratch with no open sorcery. Now everyone seems to be in the club!

10 years ago I was flying and posting videos here developing my own autopilots and autonomous vehicles. Eventually this lead into a full time career in drones and ultimately landed me here at CyPhy works! Maybe others out there want to do this for a…

Tj Bordelon replied to Juan Carlos Hdez's discussion sensors in the arms?
"I wouldn't discount the idea. I had my IMU in a wingtip and the accelerometers worked. I bet as accels get lower in noise, you may start to get useful rotation data-- where one wingtip accelerates up and the other down. I think the idea is sound,…"

"Right. But we were talking about how things should be I thought. Not how they are.

I think we've worn this thread out."

"Ok, I get it. Both of us agree that "this is the way it is", but you go along with it in principal while I don't.  We also disagree on whether or not the govt has the "right" to do what they do. Fair enough."

"Why do you equate what I am saying with being stupid? Please re-read my posts.
 
We as a hobby should have no less right to use the sky than a major airline. So long as we are safe about it. The rules should allow everyone to use the sky. Where I…"

"@Duane. If I want to ride my bike across the country I can. I just have to go on the sidestreets. If I want to fly to 100k feet for high altitude experiments, I CANNOT. Not in the desert, not over the ocean, not through some corridor, not with see…"

"@Duane - You have a common misunderstanding of the rights you have as an American. Seriously. It's not a God thing more than a logical operator. Let's try in C:

"@Duane - Go try to sell a UAV right now and expect your customers to operate it without hassle even though you are being totally safe.  The fact that you can't shows me the FAA is stepping on my rights.
 
Also, judging by what I've seen in these…"

"@Duane - Small correction... According to my American History class way back, We have divine rights. These rights are given by "god" and not by the government. Note that this is the the founding principal of our country! And this is not necessarily…"

"Wasn't space 50k feet less than 100 years ago? Then they moved it to 50 miles. Now it's 62. Balloons reach what is commonly called "The edge of space" by the various groups. I like that title better."

It is legal, part 101 FAA regs.

I wish I had an HD camera in 1998! This video kicks butt."

"@Ritchie - Yep, there are 3 or so versions of that camera. I am able to set the time, but every time I hook it to the PC it resets. Thanks for the encouragement. After a crash I get depressed for a few days. I shall return!! (I guess it happens to…"

"I definitely have more reading to do. According to this book, "Principles of Flight Simulation", section on heading hold, they do exactly what you suggest. BUT- they use AIRSPEED and no atan:
